The code that I tried to type in:

[x,y,z] = textread(fid,'delimeter','\t');

is my code wrong in which areas?

textread() takes a file name as its first argument, not a file identifier. textscan() takes a file identifier.

fid = fopen('YourFileName.txt', 'rt');
datacell = textscan(fid, '%f%f%f', 'delimiter', '\t');
fclose(fid);
x = datacell{1};
y = datacell{2};
z = datacell{3};
